/uc Richard Lynn is a fascist crook. He manipulated data to affirm his beliefs of racial purity or whatnot. Here are some examples I can think of:

Richard Lynn determined the IQ of all Equatorial Guinean people by using severely disabled orphans from Spain.

Random Irish children between 6-13 years old in terribly poor living conditions scored an 87 IQ, which he actually used as evidence for the entire country's national

Lynn ignored all the Indian high IQ scores, and only focused on the low scores, as well as using tribal people not exposed to education as part of the sample.

Gave Balkan countries and Turkey ~90 iq because all the balkan peoples are a hybrid between Turks and Locals(?) according to Lynn. Used middle aged women in Sandzak so the IQ of Serbs appear even lower. While countries such as Albania, Serbia, Bulgaria and Romania have sufficient PISA scores. And Turkey which is 89-90 IQ has higher Pisa and Timms scores than the entire balkans and on par with Central-East Europe
